Purpose
A single dose of nevirapine (SD NVP) given to an HIV infected pregnant woman followed by a single dose to her infant has been shown to be an effective way of reducing the risk of mother-to-child transmission (MTCT) of HIV. The purpose of this study was to compare the effectiveness of a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral regimen versus a protease inhibitor (PI)-based regimen in HIV infected infants who had or had not been exposed to SD NVP for prevention of MTCT.

>> A five year follow up has been added to the study.

Primary Outcome Measures:
- Percent of Participants With Treatment Failure, Defined as a Confirmed Virologic Failure or Permanent Discontinuation of the Randomized NNRTI or PI Component of Study Treatment [ Time Frame: Earlier of 24 weeks or date of DSMB decision to unblind Cohort results (Coh I: April 20, 2009; Coh II: October 27, 2010) ] [ Designated as safety issue: No ]Treatment failure is defined as a confirmed plasma HIV-1 RNA level that is <1 log10 copies/mL below the study entry value at 12 to 24 weeks after treatment is initiated OR a confirmed plasma HIV-1 RNA level >400 copies/mL at 24 weeks OR permanent discontinuation of the randomized NNRTI or PI component of study treatment at or prior to 24 weeks of treatment for any reason including death. Results report percent of participants reaching a treatment failure endpoint by week 24 calculated using the Kaplan-Meier method.
Secondary Outcome Measures:
- Time From Randomization to Treatment Failure, Defined as Virologic Failure or Permanent Discontinuation of the Randomized NNRTI or PI Component of Study Treatment [ Time Frame: Until date of DSMB decision to unblind Cohort results (Coh I: April 20, 2009 - median follow-up 48 weeks and range 0 - 125 weeks; Coh II: October 27, 2010 - median follow-up 72 weeks and range from 0 to 204 weeks) ] [ Designated as safety issue: No ]Treatment failure is defined as a confirmed plasma HIV-1 RNA level that is <1 log10 copies/mL below the study entry value at 12 to 24 weeks after treatment is initiated OR a confirmed plasma HIV-1 RNA level >400 copies/mL at 24 weeks OR a confirmed viral rebound >4000 copies/mL after week 24 OR permanent discontinuation of the randomized NNRTI or PI component of study treatment for any reason including death.
- Percent of Participants Experiencing Virologic Failure [ Time Frame: Earlier of 24 weeks or date of DSMB decision to unblind Cohort results (Coh I: April 20, 2009; Coh II: October 27, 2010) ] [ Designated as safety issue: No ]Virologic failure is defined as a confirmed plasma HIV-1 RNA level that is <1 log10 copies/mL below the study entry value at 12 to 24 weeks after treatment is initiated OR a confirmed plasma HIV-1 RNA level >400 copies/mL at 24 weeks OR death on or before 24 weeks. Results report percent of participants reaching a virologic failure endpoint by week 24 calculated using the Kaplan-Meier method.

Only subjects who reached 48 weeks of follow-up before DSMB decisions to unblind each Cohort were included in summary.

For subjects in WHO Stage IV at entry, disease progression was defined as death.
- Time From Randomization to Death [ Time Frame: Until date of DSMB decision to unblind Cohort results (Coh I: April 20, 2009 - median follow-up 48 weeks and range 0 - 125 weeks; Coh II: October 27, 2010 - median follow-up 72 weeks and range from 0 to 204 weeks) ] [ Designated as safety issue: Yes ]Results report 2nd percentile of time from randomization to death

- Receiving chemotherapy for an active tumor >>
- History of a cardiac conduction abnormality and underlying structural heart disease
